Just use RainX. If you haven't tried it, do. 50mph + and you don't need to use your wipers, heavier the rain, the better it works. Only downside is you do need to reapply every few months. But once it's on regularly,bit stays on for longer. And if you use the RainX glass cleaner, even better. I also use the screenwash additive. Wouldn't go back to not using it on the car.
This one gets mixed reviews https://www.amazon.co.uk/Rearview-P...2VCFPGD3SGQN&refRID=2XS1ZWXA2VCFPGD3SGQN&th=1
@SprinterII, living in the desert I’m not sure I need this particular product. But your thread title captures my general motorcycle “stuff” mantra. I. NEED. THIS.
Honestly don't suffer from that. In fact, my Freelander without it is horrendous. Tried allsorts to remove similar effect you describe, fixed it by using RainX. That was the original reason for purchasing it.
Also great on frosty morning, just Chuck warm water on the screen, all slides off and left with dry clear screen
